Debug Error - Object Variable Or With Block Variable Not Set -
Feb 15, 2006
I keep getting this debug error, see my code below, I have gone thru it time and time agian and do not see where the problem is. I have checked and have no NULL values that I'm trying to write back.

i am using a OLE DB Source in my dataflow component and want to select rows from the source based on the Name I enter during execution time. I have created two variables,
enterName - String packageLevel (will store the name I enter)
myVar - String packageLevel. (to store the query)
I am assigning this query to the myVar variable, "Select * from db.Users where (UsrName = " + @[User::enterName] + " )"
Now in the OLE Db source, I have selected as Sql Command from Variable, and I am getting the variable, enterName,. I select that and when I click on OK am getting this error.
Error at Data Flow Task [OLE DB Source [1]]: An OLE DB error has occurred. Error code: 0x80040E0C. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E0C Description: "Command text was not set for the command object.".
Can Someone guide me whr am going wrong?
myVar variable, i have set the ExecuteAsExpression Property to true too.
I want to use a ForEachLoop. I've an object variable what i fill before going into the ForEachLoop. It contains 4 columns and in my testscenario it has two rows. In the ForEachLoop i want to set the current row values to 4 package variables (within package scope).
So i set the Enumerater as "Foreach-ADO-Enumerator", the Ado-source-variable is my objectvariable (what contains the recordset), and the enumerator-configuration i set to "rows in all tables" ("rows in the first table" works with equal result).
The variable-mapping looks like that:
Mypackvar1 - Index 0 Mypackvar2 - Index 1 Mypackvar3 - Index 2 Mypackvar4 - Index 3
Seems to be really simple, but always i get into my first parameter the value "0" - what is not in my record set (i am relatively sure).
Am i on the right way? Is it great bullshit what i am doing?
I have some SSIS variables of type System.Object (they have to be this type because they are used to hold the results of a single row result set in an Execute SQL task which is querying an Oracle database. Although I know the Oracle table columns are Numeric, this was the only SSIS type that worked).
My problem is that I want to use these variables in expressions, but can't - I get the error "The data type of variable "User::varObjectVar" is not supported in an expression".
The only workaround I can think of is to use a script to assign the numeric values (integers, in fact) that these variables hold to other variables of type Int32.
Is that my only option, or am I missing something?
I have a custom task to execute a package. This task sets dynamically the values of the child package at runtime before execution of the child.
Everything works fine, as long as Im not trying to use an Object Variable in the child package, trying to fill with an ArrayList. Then, during package validation at runtime, the Properties of the custom task have NULL-Values. I don't know why all Properties got NULL or 0 (int), only adding an ArrayList-Property to the Task-Code.
The ArrayList gets initialized in the constructor of the Task. Values to add in execute(). But the process never gets to the execute()-Method, due to my check in validate() for null Values. So the List is initialized but empty.
Anyone an idea, maybe I'm doing something wrong at all. Anybody experiences with Object-Variables in Packages? A HowTo?
I have an application where the columns in a datatable stored in a variable (as a dataset with one table in it) are dynamic. This means that the number of columns and their data types will vary. Also, I would like to access the column names. For these reasons it is not very practical to map the columns to variables.
Is there a way to use a Script Task within a For Each Loop (with ADO enumeration) to read the data row by row (presumably as a datarow) getting the column names and coloumn values by numeric (column) index?
I have one scenario. I am calling all columns result set to an variable and inside for each loop container using script task to get message about how many columns are coming in the loop.
At last using send mail task to send automated mails to group of people,but issue it is taking only person's mail id and coming out of loop.
Hello, I have a 'ForEach Loop Container' that does a select from a table and I use Variable Mappings to map each row set result to Package Variables in SSIS. This works fine. However, in the Data Flow, I have a Script component in which I need to access the values of those variables that have been set in the ForEach Loop Container. How do I do this?
Perhaps I'm on the wrong track but I guess I need to access the ADO Object Source variable set in the ForEach Loop Container? Through my own experimentation, I know that accessing the VariableDispenser collection only returns whatever default values that happen to be assigned to the variables in the SSIS GUI (not the values assigned during each iteration of the ForEach Loop).
I have a script component that contains a script similar to that shown below;
Public Sub Main()
Dim sqlConn As New SqlConnection("Server=myserver;Database=mydb;Trusted_Connection=True;")
Dim SQLStmt As String
SQLStmt = "select top 10 CountID from mytable"
Dim sqlComm As New SqlCommand(SQLStmt, sqlConn)
sqlConn.Open()
Dim r As SqlDataReader = sqlComm.ExecuteReader() While r.Read()
Dim MyValue As Integer
If r("CountID") IsNot DBNull.Value Then
MyValue = CInt(r("CountID "))
' HERE I WANT TO WRITE MyValue TO A PACKAGE VARIABLE AS A ROW
End If
End While
r.Close() sqlConn.Close()
Dts.TaskResult = Dts.Results.Success
End Sub
Once i have a value assigned to MyValue, I want to write this as a row to a variable (DATATYPE Object Value VALUE System.Object) in the package which will be an ADO Recordset Destination that i can then loop through later.
Im pretty new to Scripting in SSIS, but i have worked a fair bit out already, although i am stuck with the following problem.. If anyone can help out that would be great!!
Ok, i have a package that loops through records in a table, and extracts the detailed lines in a For Each loop. and stores them in a variable called DetailRecordSet with an data type of object.
I have a built a script task so that i can send out an email confirmation for each order, and i want to list the details in a HTML Table in the body of the message ( I have read that the standard send mail task wont support this, but found an example of using .NET code to generate the email message which will support it) .
What i want to know is how do i reference the columns in the Object variable so i can extract each line and add it into my string that i am creating with HTML codes.. I
e:( str = "<TABLE> <TR>" + Cstr(Variable for 1st column in recordset) + " </TR>"
if any can help my, that would be most appriciated.. Ive tried all different things that ive found on the net, but nothing is working.
I hope this is a simple question. I have a package-scope user variable which is populated using a Recordset Destination in a Data Flow task. I am attempting to read the variable multiple times from different Script Tasks. The first read works fine, however the second read, in the second Script Task, says that there are no rows.
Has anyone run across this before? Any thoughts would be appreciated.
I have a SSIS package that has a SQL task which gets a result set and stores it in an SSIS object variable. The package then iterates through that result set in a foreach Loop Container. In the loop container I have a script task and a Send Mail Task. The script task sets the contents of the email message (through an SSIS String variable). In the dataset I have an EmployeeCode column. I need to select a single EmployeeCode and grab all the records associated with that code to create a single EmailMessage for that Employee that includes all their records. I've got that done, however the way I'm implementing it I then have to update the SSIS Object variable that holds the result set to remove those records I've already processed. Doing this causes an error at the next ForEach loop iteration stating it can't find a source.
Result Set from SQL Query (16 columns, 674 rows, 145 distinct Employeecodes) Employee Code EmailAddress Other columns 1 email1 set1 1 email1 set2 2 email2 set3 2 emial2 set4 2 email2 set5 etc etc etc
The first iteration should be sent to email1 where the body includes set1 and set2, the second iteration sends to email2 where the body includes set3, set4, and set5 and so forth.
The SSIS ForEachLoop Container is looping through the entire Result Set and passing into the .NET Script task the EmployeeCode (readonly) and the entire Result Set (readwrite) and setting the value of EmailMessage. So I create the value of EmailMessage based on the EmployeeCode and then use the value of Email1 and EmailMessage in the SendMail Task. I was trying to delete the rows I processed so I don€™t process them the next time the ForEachLoop Executes (otherwise I'll get duplicate emails).
Or if there's a different way to do this, I'm open to that as well.
See below for the code I'm using (colEmployeeCode is a ReadOnlyVariable and rsRecipients and EmailMessage are ReadWriteVariables in the Script Task).
Public Sub Main() Dim Header As String Dim Body As String Dim Footer As String Header = "blah"
Footer = "blah"
Try Dim olead As New Data.OleDb.OleDbDataAdapter Dim dt As New Data.DataTable olead.Fill(dt, Dts.Variables("rsRecipients").Value)
For Each row As Data.DataRow In dt.Rows If UCase(Trim(row("EmployeeCode").ToString())) = UCase(Trim(Dts.Variables("colEmployeeCode").Value.ToString())) Then Body = Body + "Label: " + Trim(row("colum").ToString()) + System.Environment.NewLine row.Delete() End If Next Dts.Variables("rsRecipients").Value = dt Dts.Variables("EmailMessage").Value = Header + Body + Footer Dts.TaskResult = Dts.Results.Success Catch ex As Exception Dts.TaskResult = Dts.Results.Failure End Try End Sub
I have a object variable named "UserList" which gets populated through execute sql task - stored procedure.I wish to concatenate all the values in "UserList" using ssis script task - in lang vb.Output should be like (User1,User2,User3,....)
I've encountered a new problem with an SSIS Pkg where I have a seq. of Execute SQL tasks. My question are:
1) In the First Execute SQL Task, I want to store a single row result of @@identity type into a User Variable User::LoadID of What type. ( I tried using DBNull Type or Object type which works, not with any other type, it but I can't proceed to step 2 )
2) Now I want to use this User::LoadID as input parameter of What type for the next task (I tried using Numeric, Long, DB_Numeric, Decimal, Double none of there work).
In my ssis 2012 package, I have a 'object' type variable with some table like records. I want to do some SQL operations like insert/update on the records in another table based on this 'Object' type variable records. Basically I want to use a MERGE statement with another physical table with the records in the 'Object' type variable.how to map/use the Object type variable in Execute sql task.I am not good in script task. How to utilize this Object variable in a Execute sql task? Â
I'm working on an SSIS package that uses a vb.net script to grab some XML from a webservice (I'd explain why I'm not using a web service task here, but I'd just get angry), and I wish to then assign the XML string to a package variable which then gets sent along to a DataFlow Task that contains an XML Source that points at said variable. when I copy the XML string into the variable value in the script, if do a quickwatch on the variable (as in Dts.Variable("MyXML").value) it looks as though the new value has been copied to the variable, but when I step out of that task and look at the package explorer the variable is its original value.
I think the problem is that the dataflow XML source has a lock on the variable and so the script task isn't affecting it. Does anyone have any experience with this kind of problem, or know a workaround?
I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:
DECLARE @DV INT; SET @DV = (SELECT MAX(DateValue) FROM tblTG); DECLARE @PV INT; SET @PV = @DV - 1;
I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:
DECLARE @DV INT; SET @DV = ?; DECLARE @PV INT; SET @PV = @DV - 1;
I have almost 50 references to these parameters in the query so a substitution would be helpful.
I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.
Here are the task steps.
[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.
[Execute SQL Task] - Log an entry to a table indicating that the import has started.
[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.
[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.
If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.
If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post. Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.
The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.
If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.
Otherwise it returns a FALSE value in the IsNewFile column.
SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName
IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)
BEGIN
-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.
IF (@FileCreateDate > @CreateDateInTable)
BEGIN
-- This is a newer file date. Update the table and set @IsNewFile to TRUE.
UPDATE tbl_ImportFileCreateDate
SET FileCreateDate = @FileCreateDate
WHERE ProcessName = @ProcessName
SET @IsNewFile = 1
END
ELSE
BEGIN
-- The file date is the same or older.
SET @IsNewFile = 0
END
END
ELSE
BEGIN
-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.
INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)
VALUES (@ProcessName, @FileCreateDate)
SET @IsNewFile = 1
END
SELECT @IsNewFile
The relevant Global Variables in the package are defined as follows: Name : Scope : Date Type : Value FileCreateDate : (Package Name) : DateType : 1/1/2000 IsNewFile : (Package Name) : Boolean : False
Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.

I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate. SQLStatement = exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output SQLStatement = exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output

Result Set is empty. Expressions is empty.
When I run this in debug mode with this SQL statement ... exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output ... the following error message appears.

When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.
When I run this in debug mode with this SQL statement ... exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output ... the tbl_ImportFileCreateDate table gets updated. So I know that data piece is working, but then it fails with the following message.

The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?
The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.
I am in the middle of taking course 2073B €“ Programming a Microsoft SQL Server 2000 Database. I noticed that in Module9: Implementing User-Defined Functions exercise 2, page 25; step 2 is not returning the correct answer.
Select employeeid,name,title,mgremployeeid from dbo.fn_findreports(2)
It returns manager id for both 2 and 5 and I think it should just return the results only for manager id 2. The query results for step 1 is correct but not for step 2.
Somewhere in the code I think it should compare the inemployeeid with the previous inemployeeid, and then add a counter. If the two inemployeeid are not the same then reset the counter. Then maybe add an if statement or a case statement. Can you help with the logic? Thanks!

I have a parameter which should take multiple values into it and pass that to the code that i use. For, this i created a parameter and temporarily for testing i am passing some values into it.Using a dynamic SQL i am converting multiple values into multiple records as rows into another variable (called @QUERY). My question is, how to insert the values from variable into a table (table variable or temp table or CTE).OR Is there any way to parse the multiple values into a table. like if we pass multiple values into a parameter. those should go into a table as rows.
Hello, I run the DTS to copy data from Progress to SQL Server. How can match/convert the date variables to check. The field p-date as format 'mm-dd-year' . It has the value of 10/09/2001. The field s-date as varchar format. It has the value 2001-10-09. How can use the where condition ( Select ...... WHERE p-date = s-date.)
Hello! I'm using SQL Server 2000. I have a variable which contains the name of another variable scoped in my stored procedure. I need to get the value of that other variable, namely:
CREATE table #myTable(value VARCHAR(20)) INSERT into #myTable values('@operation')
SELECT top 1 @parameterValue = value from #myTable -- Now @parameterValue is assigned the string '@operation' -- Here I need some way to retrieve the value of the @operation variable I declared before (in fact -- another process writes into the table I retrieved the value from), in this case 'DIS'
DROP TABLE #myTable
I've tried several ways, but didn't succeed yet! Please tell me there's a way to solve my problem!!!
I have an SSIS package that creates a csv file based on a execute sql task.
The sql is incredibly simple select singlecolumn from table.
In the properties of the execute sql task I specify the result set as "full result set" when I run it I get the error that: Error:
The type of the value being assigned to variable "User::CSVoutput" differs from the current variable type.
Variables may not change type during execution. Variable types are strict, except for variables of type Object.
If I change the resultset to single row then I only get the first row from the DB (same if I choose none), If I choose XML then I get the error that the result is not xml. What resultset type do I need to choose in order to get all the rows into the CSV? The variable I am populating is of type string and is User::CSVoutput
Is there any way to use a 2 dimensional array of strings as the Variable Enumerator for the "Foreach From Variable Enumerator". I am trying to copy a collection of files from folder A to folder B. In a script, I would populate, let us say, an array of (2,10), for 10 files, with one column representing the source file and other column representing the target column task. Then I would like to set this string array variable as the "Variable Enumerator" for the "Foreach From Variable Enumerator" and use file system tasks in the foreach loop to perform the tasks. The problem is that the "Foreach From Variable Enumerator" does not let me choose an index, but passes only one index 0, so, I will only be able to pass just one column. How do I let the foreach enumerator let me choose an index. The other foreach enumerators, foreach item and ADO give me the option to select index. I would like the same functionality in the foreach variable.
Note: I cannot use the "For Each File" enumerator, since the files are to be selected by a script only. Thanks for the help.
